JSON Formatter & Validator

About the JSON Formatter

Our JSON Formatter is a powerful tool for validating, formatting, and minifying JSON data. It helps developers make JSON code more readable and find errors.

The formatter checks for syntax errors, allows customizable indentation, and offers useful features such as minification and automatic repair attempts for invalid JSON data.

Use Cases

This tool is ideal for developers working with APIs, creating JSON configuration files, or debugging data. It makes complex JSON structures more readable and helps identify errors quickly.

Web developers can use it to analyze API responses, frontend developers can optimize their file sizes through minification, and testers can validate JSON data for test cases.

Features

In addition to the basic functions, our tool offers the ability to upload JSON files, copy or download formatted results, adjust indentation sizes, and show or hide line numbers. All processing is done locally in your browser – your data never leaves your computer.

Tip: Use the keyboard shortcut Ctrl+Space to automatically format after entering your JSON. If you get a syntax error, try the 'Try to Fix' function, which can often correct common mistakes like missing quotes.
